You can change your screen resolution by either right-clicking the desktop and selecting Properties, or by going into the control panel and clicking the Display icon. You will then click the Settings tab. In Vista, you will find the monitor settings under the Personalization icon, then the monitor tab.

Next, look for the slider bar that says Resolution. Be careful not to set the resolution too high, as older monitors may not be able to handle the resolution and could possibly go black. If this happens, do nothing, as Windows will usually revert the resolution back after 15 seconds without a response from you. Typical resolutions are 800X600 or 1024X768. If you have a wide screen monitor, you can even try 1280x768.
